无法在pyhton中使用base64编码的数据 [英] Not able to use base64 encoded data in pyhton

问题描述

所以我有这段代码，该代码使用base_64编码的数据(图像数据)，将其转换为图像并在其上运行google vision(OCR).但是base_64编码的数据存在一些问题.即使认为它是正确的，它也会引发以下错误.

So i have this code which uses a base_64 encoded data(image data) , converts it into an image and runs google vision (OCR) on it . But there is some issue with the base_64 encoded data . Even thought it is correct it throws the following error .

无效的base64编码的字符串:数据字符(167737)的数量不能超过4的倍数1

Invalid base64 encoded string: number of data characters (167737) cannot be 1 more than a multiple of 4

因为该字符串是2000行，所以我无法在此处输入它， b'/9j/4af ..... TE2f//Z'就是这样开始和结束并包含167737个字符.所以我现在该怎么办，因为即时通讯无法将其转换回图像文件.只是为了测试代码，我使用的是我转换为base_64的图像，并使用该字符串将其传递给其他代码，该代码应该在转换后的图像上运行ocr后为我提供文本输出.

Since that string is 2000 lines i cannot input it here , b'/9j/4af..........TE2f//Z' this is how it starts and ends and has 167737 characters in it. So what do i do now as im not able to convert it back to image file . And just to test the code i am using an image which i converted to base_64 and using that string to pass it to a different code which is supposed to give me the text output after running ocr on the converted image.

推荐答案

添加缺少的填充.

padding = len(data) % 4
if padding > 0:
    data += b'='* (4 - padding)
base64.b64decode(data)
